用于医疗建筑物的余热回收型空调系统
By using a waste heat recovery air conditioning system, heat exchange coils are used to absorb heat from the UPS room, solving the problems of high energy consumption and difficult outdoor unit installation in the air conditioning system of the UPS room in medical buildings. This achieves 100% fresh air operation and reduced energy consumption, improving the efficiency of the air conditioning system and air quality.

AI Technical Summary
The air conditioning system in the UPS room of medical buildings has problems such as high energy consumption and difficulty in installing the outdoor unit. Especially during the transition season, it is impossible to achieve 100% fresh air operation, which affects the efficiency and energy consumption of the air conditioning system.
The waste heat recovery air conditioning system absorbs heat from the UPS through a waste heat circulation loop, and uses heat exchange coils to reheat the cooling air during the cooling season, preheat the mixed air during the heating season, and operate with a large fresh air volume during the transition season, thus solving the installation difficulties and energy consumption problems of the outdoor air conditioning unit.
It reduced the energy consumption of cold air reheating and mixed air heating, solved the installation problem of the outdoor unit of the air conditioner in the UPS room, and enabled the operation of fresh air in key departments, thus improving the efficiency of the air conditioning system and the air quality.
